Detailed explanation-1: -Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size.

Detailed explanation-2: -An autosome is one of the numbered chromosomes, as opposed to the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes (XX or XY). Autosomes are numbered roughly in relation to their sizes.

Detailed explanation-3: -Autosomal means that a specific gene is not on a sex chromosome and is a numbered chromosome. Humans have 46 total chromosomes. Each of your parents gives you 23 chromosomes via the egg or sperm, for a total of 46. There are two sex chromosomes (X and Y) and 22 numbered chromosomes.

Detailed explanation-4: -In plants and animals (including humans), chromosomes reside in the nucleus of cells. Humans have 22 pairs of numbered chromosomes (autosomes) and one pair of sex chromosomes (XX or XY), for a total of 46.

Detailed explanation-5: -Each cell of your body typically contains 23 pairs of chromosomes. Out of each pair, one chromosome is inherited from your mother and the other from your father. The first 22 pairs of chromosomes are referred to as autosomes and are the same between males and females.
